Not to worry. Lice need a living host to survive, as they need to eat blood. Most don't live more than a day off a person's body, so they can't live in your car long! proper hygiene & laundering clothes infested with body lice usually takes care of the problem. Head lice will not infest your car, nor will pubic lice; they live on hair-bearing skin. Worst case, vacuum & stay out of the car for a few days.
